4 types of stone crushers' maintenance and efficient improvement | fote machinery

There are different types of stone crushers in mining industry such as jaw crusher, cone crusher, impact crusher, and sand making machine. This article will tell you how to maintain the 4 types of rock crushers and how to efficicently improve their performance.

Many stone crusher operators have a common coception that is "don't-fix-it-if-it-isn't-broke". They may want to save cost at the begining while the consequence is that they have to spend more money on repair and face interuption on production. That's why I always say that preventive and predictive is very important for all types of stone crusher.

Preventive means that by making regular checklist and inspections to keep crushers in good condition. Maintenance checklist is usually set up on a daily (8 hours), weekly (40 hours), monthly (200 hours), yearly (2,000 hours). Only doing that, can you prolong the machine's life span and maximize its value in crushing process.

Predictive refers to mornitoring the condition of crusher when it is running. By some maintenance tools such as lubricating oil temperature sensors, lubricating oil filter condition indicator, you can timely draw the machine data so that making a comparison between the real situation and normal state. Predictive can help you find problem early then timely removing thers issues before demage occuring.

Ractive means that even if your crushers have got problems, as long as you adopt correct solutions to respond, you still can get your machine back to normal. Next, I'll introduce important skills to maintain your equipment.

The cone crusher in the secondary or tertiary crushing proccess often fractures medium-hard or hard rocks like pebble, quartz, granite, etc. It is easy to get premature crusher failure, if operators cannot make a correct and timely inspection and maintenance.

Mantle in moveable cone and concave is fixed cone. Due to directly contacting with rock materials, the two wear parts need frequent maintenance and protection. So operators have to know the preparations and maintaining skills.

The working principle of impact crusher is that the spinning rotor under the driving of the motor can genetate strong impact force which make blow bars crush stone material into small pieces. Then the crushed material would be thrown by hammers towards, which makes another crushing process "stone to stone".

The sand making machine is also known as the vertical shaft impact crusher. Its working mode is that the material falls vertically from the upper part of the machine into the high-speed rotating impeller. The impeller is one of the important parts of the sand making machine, and it is also the most vulnerable part.

After the materials collide with each other, they will be pulverized and smashed between the impeller for multiple times and discharged from the lower part. The materials crushed by the device have an excellent particle size and are suitable for aggregate shaping, artificial sand making and highway construction.

second hand stone crusher reduce operating cost of the line

second hand stone crusher reduce operating cost of the line

In the current crusher market, the price of equipment is basically stable, but subject to various factors of instability, the price of crusher will have all kinds of floating. Many factors affecting the price of crusher, such as the price of steel, the price of ore, the price of building materials, and even the price of house also will affect the crusher industry, thereby affecting the crusher offer. Currently, the price of the crusher is mainly affected by the steel, market dynamics and other reasons. According to the analysis, on the one hand, the steel stock market of this year is serious and steel prices rebound, which directly pushed up futures prices of steel. On the other hand, the more reality market mentality is the other important aspect. The mentality of most traders is tending reality. They make a large stockpile no longer, but pay more attention on the exploration to meet the potential needs of markets. Based on these factors, we can deduce that there will be some growth on stone crusher cost in the next period of time.

Compared to the new crusher on the market, second hand stone crusher may have been used for a period of time, but it still has a great advantage. Generally, all the second hand stone crusher have purchased by the manufacturers for re-sale. It has been installed and used by the first user who was forced to sell it out again because of various reasons. Therefore, second hand stone crusher has a number of advantages.

Firstly, after a period of use, the equipment installation is completed and all aspects of performance is normal, which will make it run more smoothly. This effectively avoid the initial run-in phase of new equipment, making the device available to put into use directly after purchase and reducing the time for commissioning and trial run. Secondly, the re-sale of second hand stone crusher make its usual price is not very high. Compared with new crusher, its lower price reduces the cost greatly. Thirdly, the price of new stone crusher on the market changes with a variety of uncertainties, while the price of used crusher is basically stable. Meanwhile, it has all of the performance of the new crusher.

Compared with crusher in the industry, second hand stone crusher also includes a variety of types. Equipment with different Crushing principle can meet different final products size requirements. Some can be used as primary crusher for coarse crushing of various materials, such as second hand jaw crusher. Some can be used as secondary crushing machine for intermediate crushing of medium hard and brittle materials, for example second hand impact crusher. Others can be used as tertiary crushers for fine crushing of the hard materials, such as second hand cone crusher. For another as second hand roll crusher, second hand compound crusher, we can adjust the discharge port of the device to control the particle size until meet the production needs. Therefore, the application of the crusher is very wide, especially in many small sand production lines.

Stone crushing production line also called sand production line. It is normally comprise vibrating feeder, jaw crusher, impact crusher, cone crusher, vibrating screen, belt conveyor, sand washing machine and other components. Composed by a variety of second hand, the production line can also crush a variety of rock, sand and gravel into various size of building sand, which has uniform particle size, high strength, cubic shape and needles, flakes product content is low. The sands are more in line with the high standard building requirements than the natural sand and it is better at improving the quality of water conservancy construction, bridges, senior highways, high-rise construction and other industries. Depending on the process requirements, the line will be configured with the appropriate equipment to play its best performance. The production line consisting of second-hand equipment also has a series of advantages, such as high degree of automation, large output, less pollution, easy to operate, crushing rate, saving energy more than 20%, reducing the operating cost.
